view thereof, the interior mechanism being hown in. elevation. Fig. 3 is an enlarged ragmentary sectional view through the casing showing the mechanism in section. Fig, 4: is a cross sectional of Fig. 3, and. Fi 5 1s a fragmentary side elevation of one si e wall of the casing. Referringnow to the accompanying draw- Beit known that 1, Joanna H. SMEDLEY, a citizen of the United States, residing at Narb erth, in the county of Montgome and State of-Bennsy-lvania, have invents new and useful Improvements in'Push-Button Switches, of which the following is a specification.

switches for closing the circuits of electric bells and other analogous which screws or otherfastening devices are be passed so that the base may fastened upon a suitable or convenient object, .while 2 designates a face plate having formed integral with the marginal edges thereof side and end walls provided with inturned flanges 3 adapted to contact with the front face of the plate 1, the plate 1 and flanges 3 being n.cavrying out the present invention, it is my purpose to rovide a push button switch which wi-lhhe in the nature of a combination circuit-closer and electric lamp,

by-the circuit closer and capable of illumination so that the hell or other annunciator circuit vcontrolled by the circuit closer may be readily night.

purpose. toprovide a novel for making and breaking the lamp may be 'n accordance end walls formed integral therewith and the plate 1 constitute a housing or casing. .If ired, suitable indicia, such, for instance, as the. number ofv a house in which the device is-install ed. may be inscribed upon the front; face of the plate 2.

.The front plate 2 of the casing, atan appropriate point, is formed with an opening annunciator cir- ,whil ted forsliding and at the-circuit vcloser may' -be opened and closed .and the lam connected in and output of the circult thereof respectively when necessa It is also. .my intention to rovil a push button switch which may illumipated w an conditions warrant, as instance, in the night time so that the push button may be readil and conveniently located t is also my form of switch the lamp circuit sothat si with prevailing conditions.

Furthermore, I aimfto provide a push button switch embodying Jnits construction among other features a circuit closer ada lug. are brackets-6 suitably spacedvapart and carrying an annulus 7 preferabl of insulating material and disposed coaxial with the opening 5' in the plate 2. Mounted within the annulus 7'for longitudinal slidingand rotary movements therein is a relaly narrow ring 8 composed of some suitah amaterial and carrying a relatively long threaded socketmember 9 extending beyond the confines of'theannulus and threadedly receiving a metallic plug 10 carrying an electric .lamp bulb 11 disposed .within the opening 5 and capable of sliding movement in such opening and rotary movement therein. Suitably fastened to the rear wall of t e casing or housing formed of the base plate 1 and preferably coaxial with the opening 5. in the front wall of such casing. is a stationary contact 12 adapted to be engaged by a spring contact 13 having one terminal or end suitably fastened to the .rear wall .of the casing, while the opembrace. the desired features .of simplicity, .efiiciency and durability coupled with .1: ness of cost in manufacture and installation.

With the above and other objects in view, the invention consists in:the..construd;ion, combination and arrangementof parts .hereinafter set forth in and'falling within the scope of the claims.

In the accompanying drawing; Figure 1 is a plan view of a push button switchconitructed in accordance with my esent .inzention. Fig. 2 is a longitudina sectional view on the line 2. A device of the class described com ris ing a casin having an opening in the ent wall thereo an annulus disposed within the casing coaxial with the opening therein, a ring disposed within said annulus and capable of sliding and rotary movement therein, a lamp carried by said ring and normally projecting out of the casing by way of the opening therein, a pair of contacts disposed within the casing in the path of sllding movement of said lamp, an annunoiator circuit including said contacts and adapted to be closed when said lam is moved inwardly of the casing, a switch or closing the lamp circuit when the lamp is rotated, and means for rotating said lamp whereby the switch will be closed.

3. A device of the class described comprising a casing having an opening in the front wall thereof and formed with a slot in one side wall thereof, an annulus disposed within the casing coaxial with the opening therein and having a slot formed therein alining with the slot in the side wall of said casing, a ring disposed within said annulus and capable of sliding and rotary movement therein, a lamp carried by said rin and normall projecting out of said casing by way of t e opening therein, a pair of contacts disposed within the casing in the path of sliding movement of the lamp, an annunciator circuit including said contacts and adapted to be closed when said lamp is moved inwardly of the casing, a switch for closing the lamp circuit when the lamp is rotated, and a manipulating handle for said switch connected to said ring and extending outwardly of the casing by way of the slots in the annulus and in the side wall of the casing.

4. A device of the class described comprising a casing having an opening in the front wall thereof, an annulus disposed within the casing coaxial with the opening therein, a ring disposed within said annulus and capable of sliding and rotary movement therein, a lamp carried by said ring and normally projecting out of the casing by way of the opening therein, a pair of contacts disposed within the casing in the path of sliding movement of said lamp, an annunciator circuit including said contacts and adapted to be closed when said lamp is moved inwardly of the casing, a switch for closing the lamp circuit when the lamp is rotated and comprising a pair of contacts secured to the outer surface of said annulus at diametrically opposite points, and a pair of contacts secured to said lamp at diametrically opposite points and rotatable therewith to engage the first-mentioned contacts, and means for rotating said lamp whereby the switch will be closed.

In testimony whereof I affix my signature in presence of two witnesses.
